According to A,B,C, we find that if the a pole is far away from the imaginary axis,
it wont influence the system a lot. So the value of is 0.1.
(Answer the smaller the better is also Ok ).

II.C. Steady State Tracking and System Type
Ability of a control system to track (or follow) given input?

System
y(t)
i.e., will e(t ) r (t ) y(t ) 0 for t large?
Some general ideas - by applying step, ramp, and parabolic
inputs to Unity Feedback S

III.B.5 Stability Analysis with G( j )
Contour Mapping
- F(s) is any function of complex variable s
- s is any contour in s-plane
- Contour F formed by mapping every point si on s
to become a point F(si ) in F(s)-plane
